===Polyscalarity===

Polyscalarity is defined as "the simultaneous use of musical objects ''which clearly suggest different source-collections''.{{sfn|Tymoczko|2002|loc=83}} Specifically about Stravinsky's music, Tymoczko uses the term polyscalarity out of deference to terminological sensibilities.{{sfn|Tymoczko|2002|loc=85}} In other words, the term is meant to avoid any implication that the listener can perceive two keys at once. Though Tymoczko believes that polytonality is perceivable, he believes polyscalarity is better suited to describe Stravinsky's music. This term is also used as a response to Van den Toorn's analysis against polytonality. Van den Toorn, in an attempt to dismiss polytonal analysis used a monoscalar approach to analyze the music with the [[octatonic scale]]. However, Tymoczko states that this was problematic in that it does not resolve all instances of multiple interactions between scales and chords. Moreover, Tymoczko quotes Stravinsky's claim that the music of ''[[Petrouchka]]''{{'}}s second tableau was conceived "in two keys".{{sfn|Tymoczko|2002|loc=85}} Polyscalarity is then a term encompassing multiscalar superimpositions and cases which give a different explanation than the octatonic scale.
